Replaced fuel pressure regulator now the car cranks but won't start. It has also been sitting for about 6-10 months. Made sure fuel was getting to the regulator be for I even connected it.

Hi,

It could be a couple of different things. I need you to try something for me. Will the engine start for a couple of seconds and then stall if you use starting fluid? If it does, then we know it's a fuel-related issue.

If starting fluid makes no difference, then it is likely related to the ignition system. With no change using starting fluid, we need to check for spark to the plugs. Here is a link showing how it's done.

Try this and let me know the results.

Take care,

Joe
